I've recently started doing some work on RFID and I would also love to get my Z talking to an RFID reader/writer. Especially because for in the field a self contained reader is easy enough to design but a reader/writer would need something like the Z to be able to make changes.

All of the research I've done points to that none of these tools are working on the Z yet. I might try to do some work on the software if I can get the hardware to work better on its own first.
